Meaning
賢 means wise, clever, sagacious, and virtuous — but raw intelligence alone doesn't cover it. The character implies something deeper: sharp thinking paired with moral integrity. In Japanese culture, a 賢い人 (kashikoi hito) earns admiration for both intellect and sound judgment, not one without the other.
Structurally, 賢 has two main parts. The upper component is 臤 — a combination of 臣 (a minister, originally depicting downcast eyes symbolizing focused duty) and 又 (a hand, representing skill and action). Together, 臤 suggests someone who works firmly and capably. Below sits 貝, the kanji for "shell," which in ancient times served as currency and treasure. The full character depicts a skilled, dutiful person managing something precious — wisdom understood as knowing how to handle what truly matters.
With 16 strokes, this is one of the more complex kanji at N2 level. Classified as a secondary school (grade 8) kanji in Japan, it appears regularly in essays, news articles, and literature — anywhere the topic involves admirable people or sound decisions.

Memory Tip
Start at the bottom of 賢: 貝, the shell. In ancient Japan, shells were real currency — precious and portable. Now scan upward: 臣, a minister with downcast eyes fixed on duty, paired with 又, a skilled hand ready to act. The character shows a capable person tending to something of value. That's 賢. A quick hook to anchor it: "A wise (賢) person watches the treasure (貝) with steady hands (又)." Spot those shells at the bottom, and the meaning snaps back immediately.
